The Cell Theory: From Hooke to Virchow

The video tutorial explores the history and development of cell theory. It begins with Robert Hooke's discovery of cells in cork using a simple microscope in 1665. Antonie van Leeuwenhoek's subsequent identification of microorganisms, including bacteria and yeast, further advanced the understanding of cells. The video then discusses the contributions of Theodor Schwann and Rudolf Virchow in the 19th century, who established the foundational principles of cell theory: all living organisms are composed of cells, the cell is the basic unit of life, and all cells arise from pre-existing cells.
